摘要： A file system that does not require unique item names, or any item name at all, is described herein. If an item has an ambiguous name, the file system performs a disambiguating procedure to provide the client (user or application) a conceptually unique name, including a fully qualified path. The file system provides usability features such that the file system maintains compatibility with legacy applications and systems, including creating a synthetic item name when the item has no name, and disambiguating two items having the same name by using a disambiguating character, such as a small integer or alphanumeric character.
摘要翻译：本文描述了不需要唯一项目名称或任何项目名称的文件系统。如果某个项目具有不明确的名称，则文件系统将执行消歧义过程，以向客户端（用户或应用程序）提供概念上唯一的名称，包括完全限定的路径。文件系统提供可用性特征，使得文件系统保持与遗留应用和系统的兼容性，包括当该项目没有名称时创建合成项目名称，以及通过使用消歧字符来消除具有相同名称的两个项目，例如小的整数或字母数字字符

摘要： A file system that does not conflate item lifetime with the item's inclusion in an organizational structure of the file system is described herein. In addition, the file system's organizational structure is not limited to directory trees, but instead may use any directed acyclic graph (DAG). Items, once stored into the file system, may be maintained until affirmatively deleted by a client of the file system, regardless of whether the item is part of a DAG or not. Items may be placed in file regions, which are conceptual workspaces for a client to control item lifetime and to organize items into any DAG structure of the user's choosing. Items may be concurrently stored in multiple DAGs, and each file region may have one or more independent DAGs. An item's placement in a DAG may also be used to govern file properties such as namespace, security, privacy, and read/write attributes.
摘要翻译：这里描述了不将项目生命周期与项目包含在文件系统的组织结构中的文件系统。此外，文件系统的组织结构不限于目录树，而是可以使用任何有向无环图（DAG）。一旦存储到文件系统中的项目可以被维护，直到由文件系统的客户端肯定地删除，而不管该项目是否是DAG的一部分。项目可以放置在文件区域中，这些是客户端的概念工作区域，用于控制项目生命周期，并将项目组织到用户选择的任何DAG结构中。项目可以同时存储在多个DAG中，并且每个文件区域可以具有一个或多个独立的DAG。项目在DAG中的放置也可用于管理文件属性，例如命名空间，安全性，隐私和读/写属性。

摘要： Mechanisms and techniques for database fragment cloning and management are provided. A database object, such as a table, rowset or index, is divided into fragments. Each fragment is cloned to create cloned fragments, which operationally are substantially identical to one another. One or more of the cloned fragments may be designated as a primary cloned fragment for performing database operations or as a secondary cloned fragment for serving as backup. Updates to each fragment are implemented on the primary cloned fragment and are then propagated from the primary cloned fragment to the corresponding secondary cloned fragments. A cloned fragment can go offline, becoming unavailable to be updated. When the cloned fragment returns online, the cloned fragment is refreshed with data included in the primary cloned fragment. While being refreshed, the cloned fragment may continue to be updated. The cloned fragment is eligible to be designated as a primary cloned fragment when the refreshing process has been completed.

摘要： Methods and computer-readable media for maintaining transactional link-level consistency between a database and a file system. A file system change is logged in a record of a database log and a file corresponding to the file system change is created in a file system folder. During a restart recovery process, an analysis operation and a conditional redo operation are performed based on the database log, and a conditional redo operation and an undo operation are performed based on the files in the file system folder. An undo operation is then performed based on the database log.

摘要： A type of an object that can be persisted in a database store is defined by a user. The type definition comprises fields and behaviors, each field having a respective data type. One or more fields of the type definition may be designated as containing data of a type that is to be stored as a file outside of the database store and separately from the other fields of the type definition. When a request is received to store an object that is an instance of the user defined type, the data in any so designated field of the object is stored in a file outside of the database store, preferably within a file system of the computer on which the database store is implemented. The data in each of the other fields of the object is stored within the database store in the usual manner. The database store maintains a link, or reference, between the persisted object and the data of the field that is stored as a file outside of the database store. Applications are provided “out of band” access, via the file system of the computer, to the file in which the data of given field is stored outside the database store.
摘要翻译：可以在数据库存储中保存的对象的类型由用户定义。类型定义包括字段和行为，每个字段具有相应的数据类型。类型定义的一个或多个字段可以被指定为包含要作为数据库存储之外的文件存储的类型的数据，并且与类型定义的其他字段分开。当接收到用于存储作为用户定义类型的实例的对象的请求时，对象的任何这样指定的字段中的数据被存储在数据库存储之外的文件中，优选地在计算机的文件系统内实现数据库存储。对象的每个其他字段中的数据以通常的方式存储在数据库存储中。数据库存储在持久对象和作为数据库存储之外的文件存储的字段的数据之间维护一个链接或引用。通过计算机的文件系统将应用程序“带外”访问提供给数据库存储之外的给定字段数据的文件。

摘要： A system and method for expediting the replication of at least one specified object to a replica in a distributed computer system. A source object of a source replica determines that it has an urgent change to propagate through the distributed system, and informs a replication facility at the source replica of the urgent change. The facility extracts, or is provided with, the change information from that object, and the source replica communicates information representative of the change to a destination replica. A replication facility at the destination replica provides the change information to a destination replica object, which uses the information to make itself consistent with the source replica object.

摘要： The present invention relates to a system and methodology to facilitate security for data items residing within (or associated with) a hierarchical database or storage structure. A database security system is provided having a hierarchical data structure associated with one or more data items. The system includes a security component that applies a security policy to the data items from a global location or region associated with a database. Various components and processes are employed to enable explicit and/or inherited security properties to be received by and propagated to the data items depending on the type of data structure encountered or processed.

摘要： A method and system for providing state-full access to files and resuming access should a connection be broken. A resume key is returned to the client that allows the client to request a duplicate handle to an open file. The duplicate handle can be used to access the file in the same manner as the handle used to open the file. When a connection is broken, the file remains open on the server for a period of time and the state information associated with the file is maintained. Even if a connection is not broken, a client may request one or more duplicate handles and establish other channels (also known as connections) with which to access the file.

摘要： Administering digital security is disclosed. Data and method items are stored on a computer system in a volume. The volume is divided up into non-overlapping security zones. Each item exists in a security zone. Security rules are granted to principals where the security rules apply to items in a particular zone. The security rules specify what principals have what rights; such as read, write delete and execute; to what items. Administrative rights can be delegated by principals by splitting a security zone to form two security zones. Principals who have administrative rights to the security zone assign additional principals to one of the security zones while maintaining all administrative rights to the other zone. Thus principals can retain certain administrative rights to certain items exclusively to themselves while delegating administrative rights to other items to other principals.
